Using HD2 for multi OS require skill & effort for hackin & flashing, HD2 not for the fainted heart.
Worth ? beside low quality camera, its really worth & quite stable.

Which OS u purpose to used anyway ?

I found HD2 usefull for Garmin XT navigation when running winmo OS, Iv living 5 years through winmo 2002 - 6.5, HD2 is the last & fastest winmo device when running Garmin XT, it even faster than Garmin GPS itself.
Though I miss alot winmo Sense UI compare to Sense Android version

1-Running winmo default from Nand & running Android from sd card will have slight delay response, some lag occur when shut down & turn off devices. Getting android is like copy the folder & execute the command files (we call it haret.exe), this will not affect winmo OS because everything loads from memory card. Recommended for beginners

Imagining a boot sequence would be
-powerup > boot > SPL > load factory winmo rom > running android haret > exiting windows > android
-powerup > boot >HSPL > load custom winmo rom > running android haret > exiting windows > android

SPL- Sequential Program Loader - a lock loader (similar to S-on)
H+SPL - Hard SPL - unlock for installing custom rom or intend MAGLDR flashing.

-----

For method 2 or 3, it require MAGLDR boot, Rom excuted from MAGLDR either load WP7, Nand or SD

2-Running Android from Nand & other android version from SD. eg MIUI from NAND & Cynogen/Sense from SD.
This is more preferable, faster & alot stable, when using stock Android (Cynogen) and MIUI roms.

A boot sequence would be
-powerup > boot > HSPL > MAGLDR > Load Nand Android > MIUI rom
-powerup > boot > HSPL > MAGLDR > Load SD Android > Cynogen rom / etc


3-Running WP7.5 from Nand & Android rom from SD
-powerup > boot > HSPL > MAGLDR > Load WP7 > Tango 7.5
-powerup > boot > HSPL > MAGLDR > Load SD Android > Cynogen rom /etc


complicate ? have a visit here & search hd2 for video tutorials,

Running rom from sd applicable for Android rom ONLY so far, so u cannot run WP7 or winmo from MAGLDR boot / MAGLDR SD

There a 2 types for loading Android from SD,
1-loads from Winmo its executed by tapping shortcut name haret.exe,
2-loads from MAGLDR boot, no haret involved, the MAGLDR call android rom by folder specified.

Performance is similar however. Lag appear mostly when turn off & turn on immediate, ie ;ag from standbye to wakeup, let say u tapping fast the end call (on off) u'll have delay blank screen wakeup

However when the roms active (ie running on screen) sd rom would perform good as nand. Speed depends on SD card speed and rom stabilty. U can have performance SD android rom when using clean Cynogen rom but using Sense rom in SD is big no because its huge RAM consume affect the speed

Major drawback (for SD Android) roma fully running from SD card, expecting battery intensive when standbye.
Eg standby in Android SD mostly 30-60mah, Nand Android 1-6mah. Each time Android on 1st load, some lag appear due SD speed caching to RAM, eg sluggish sliding homescreen or apps list on 1st load, this mostly affect on heavy rom like Sense rom,

Im suggesting to try WP7 1st in Nand, but u need activation codes to access marketplaces. Its better to get another spare memcard because its clear everything on 1st WP7 boot, WP7 uses encryption partition, u cant access this encryption partition. However u can resize partition to put Android SD folder in the memcard (so u can run the SD android) (check out tutorial in given website)

once u bored with WP7 we talk about Android back

sorry for delay message, u know holiday

Previously we easily get the activation by email & live chat (as I do), some SDHC card not compatible with HD2, avoid the higher class, Class 4 or 6 should be ok

1-4.yes

Im sorry for delay message, PM for immediate respond

Isnt youre previous memcard has the apps installed ? this might the problem why some program not running

btw, what your MIUI youve using now ?

hey Andy long time no see
the HWA kernel by securecrt really help those folks, but flash view still in bugs, which rom do u use now ? I not yet onto ICS atm

Wah, u got 2 units HD2 ?

wp7 is very smooth but then file transfer is troublesome, memang leceh

I hate Zune & itunes alike ,

ohmy, back to GB like old days,
any words on xylograph IceCreamTosty ? I kinda love the tablet mode
Xylograph - IceCreamTosti

btw another new rom coming, but still with bugs

Blackout ICS Primo v1.0 [First Sense 4.0a for HD2

lwk523
there the lite version in there (later page), what insterest me they said its faster & lighter than sense 3.5

jerry
previous stable rom comes without HWA (hardware accerelate) but then HWA kernel coming, theyve to refine entire rom to fix the bugs, no worry Im very positively on HD2, Anyway most user use Tytung NexusHD2 & Xylograph IceCreamTosti & sportstar ICS build, read some comments in XDA before flashing

..sudah ada HTX One X

Not sure of that,
but I dont think HSPL affect radio signal because it was mean for software bootloader,
SPL = sequence program loader. Maybe u can ask Jcsy,

Iv test before the DFT Fruit cotulla rom, 3G data connection works fine. Anyway what I love most on WP7 is the 720p camcorder camera & browser stabilty.

Im using the SD version just for ... fun, lol

anyway, lotsa new android devices coming lately , kinda drool looking to HOX & SGS3 ,
are u still with HD2 andy ?

hey there,
ya lor , no user using with HD2, this thread is such lonely

Lotsa people jump to better devices, XOX, SGS3, but til now no device could satissfied me, so I choose to stay for a while, mine was 3 years still intact & no problem or faults. Anyway Is your sister trouble in winmo or android ?

I think xperia play is cool, the gamepad is handy with PSP+mobile phone experience

Oh not again,
I guess the international HD2 has these digitizer plague issue compare to US/ TMobile HD2 or perhaps my loyal on HD2 makes me lucky,

Im not in MIUI GB 2.3. its call My MIUI
http://forum.xda-developers.com/showthread...&highlight=miui

this is very2 good MIUI rom,

dlwl
Give a try with Parandroid, the only multi dpi rom, I love the tablet mode,

Kanchong
Both version capable install & runnning Android , the only different is capacity; ie internal ;TMous 1gb rom, normal/international is 512mb rom.

For beginners I suggest try Gingerbread for best evaluation, then flash the ICS to experience the benefits

try droid sail super sd

news flash !
Android 4.1 Jelly Bean ported to Transformer Pad, NOOK Tablet, HD2



[WIP] 1st ROM of JellyBean for HD2 port from N1 by Evervolv [KERN: Tytung R3.2]

its WIP=work in progress , not for daily but kinda good alpha release

I think the most important for JB is the smothness acceleration, but I kinda like the new notifications ... but waiting game is quite long lar



I can only recommend Duttys rom, the best for 6.5.x , some user still use win 6.5 for navi purpose, coz the best navi soft still Garmin XT, really love the old slide sense.
